Rhodes Key Post Lube comparison/"best" opinions?

[Wags]

Hey all! Very long time listener, first time caller, and thrilled to be an official member here!
I've been maintaining my studio boards/collection for a long time and have decided to go deeper and do some full restorations instead of quick fixes.
As a side note, long time fan of Vintage Vibe and play drums for a group led by the CT legend Chuck Chesler that performs on a very early VV EP.
Just wanted to throw that in here, since their boards are second to none, can't wait to own one someday, not to mention everyone on their team has been incredibly helpful over the years keeping me up and running!

Now, sorry to post such a lame post as my first official entry, but here's the deal, I'm looking to buy some Key Post lube in a more bulk format and do a bunch of pianos with it.
I've used and enjoyed the VV Key Post lube, but it isn't economical to buy in large quantity.

Looks like my options are:
Protek CLP - Seems to be widely used among piano techs.
Mclube 444A - Dare I say it looks and seems very...very similar to the VV lube...maybe they would recommend using over Protek?

Any thoughts on what's better, or did I miss a better option?

I promise I'll have more juicy posts soon!
Huge thanks
